概括
肺炎球菌携带率在非洲儿童中最高,对老年人的数据有限. 接种疫苗可以减少特定的血清型,但不能减少整体携带,这表明血清型的替换.
科学领域:
- 微生物学与传染病的研究
- 公共卫生 公共卫生
- 流行病学 流行病学
背景情况:
- 肺炎链球菌 (S. pneumoniae) 引起肺炎,通常是在鼻运输之后.
- 肺炎球菌肺炎的负担在低收入和中等收入国家,尤其是非洲国家最高.
- 本系统性审查审查了非洲 (2000-2021) 跨年龄组携带S. pneumoniae的决定因素.
研究的目的:
- 系统地审查和分析所有年龄段的非洲肺炎球菌携带的决定因素.
- 确定影响肺炎球菌携带的因素,包括年龄,疫苗接种状态和潜在疾病.
- 突出知识差距,特别是关于老年人口的知识差距.
主要方法:
- 对非洲肺炎球菌携带研究的系统审查 (2000-2021年).
- 提取有关群体规模,运输率,识别方法,疫苗接种情况,呼吸道感染和并发症的数据.
- 对不同年龄人口群体中肺炎球菌携带的决定因素的分析.
主要成果:
- 在5岁以下的儿童中观察到的肺炎球菌携带率最高.
- 关于老年人 (60岁以上) 携带肺炎球菌的数据有限.
- 艾滋病毒/艾滋病与携带增加相关;疫苗接种减少了特定的血清型,但没有总携带,表明血清型替换.
结论:
- 需要进一步研究肺炎球菌疫苗接种对非洲所有年龄组的影响.
- 强调研究老年人,因为老年人代表性不足和疾病负担较高.
- 研究结果强调需要有针对性的干预措施,以减少高风险人群中的肺炎球菌携带,并改进疫苗接种策略.

Factors Affecting the Risk of Infection
13.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Pneumonia I: Introduction
696
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Principles of Disease Surveillance
439
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Factors Affecting Pulmonary Ventilation
2.7K
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Factors Affecting Illness
5.0K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...
